SAFETY-RAZOR.

Specification of Letters Patent.

Patented Oct. 10, 1911.

To all whom it may concern:

Be it known that I, J osnrrr MOLKENTHIN, J12, a citizen of the UnitedStates, residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements inSafety-Razors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.

This invention relates to a safety razor which has a guard on which ablade rests, the guard having fingers to engage the top of the blade atthe side edges, and the guard thus supports the blade. A clamping plateis pivoted so that it swings against the blade and locks the bladeagainst the fingers, the preferred way being to swing the clamping plateupward against the under side of the blade and thus lock it in position.The clamping plate is forced and locked againstthe blade by suitablemeans, these means preferably consisting of a handle which is inscrew-threaded engagement with the guard.

The invention is illustrated in the accompanying drawing, in which-Figure 1 is a side view of a razor made according to my improvedconstruction. Fig. 2 is a top view of the razor with the blade removed.Fig. 3 is a section with the blade in place and with the clamping plateforced to lock the blade in position.

The razor consists of a guard 10 which has its front end elevated as at11, this elevated part being provided on its front edge with asuitablemeans for acting as a fender for the cutting edge of a blade, and isshown in the drawings as being provided with teeth 12 to provide thespaces 13 between them, the end teeth having shoulders 14: which act asstops to limit the forward movement of the blade. The blade consists ofa thin sheet of metal 15 which is sharpened on its front edge, the thinpart of the blade resting on the elevated portion 11 of the guard 10.Secured to the guard and projecting up from the sides are the fingers 16which are bent inwardly toward each other and under which the blade 15is slid before it engages the guard, the fingers and the guard acting tohold the blade in position.

A clamping plate 17 is arranged to swing on the guard, the preferredform of doing this being by means of the studs 18 which pass throughperforations 19 in the ears 20, the ears being preferably struck up fromthe guard and integral therewith. A handle 21 is provided with ascrew-threaded stud 22 which fits into a screw-threaded perforation 23in the bottom of the guard, the screw coming up through the guardunderneath the swinging or free end of the clamping plate 17 so thatwhen the handle is screwed up tight, the clamping plate is forced andlocked against the under side of the blade, which blade is then securelyheld between the fingers 16 and the clamping plate 17 The clamping plateis adapted to clear the fingers when it is swung upward to the positionshown in dotted outline in Fig. 3, when the blade is not in place, sothat the guard can be opened fully so that all parts can be easilycleaned. The front end of the clamping plate is usually eX- tendedforward far enough to be underneath the fingers 16 when in clampingposition, being permitted to pass the fingers 16 by being made narrowerthan the space between the fingers 16, as will be seen from Fig. 2.

The blades as usually made for this type of razor are made of the thinfiat part 15 with a reinforced or thickened back 24. The clamping plateis depressed as at 25 to receive the thickened back and still permit thethin part of the blade to lie substantially fiat when it is clamped sothat the blade is not subjected to any severe bending strain which wouldbe the case if the clamping plate was made fiat and the whole pressureof locking the blade was administered to the reinforced back by reasonof this reinforced part being engaged first.

This construction of razor is cheaply made, and forms a solid, rigidstructure when the parts are assembled and the handle is screwed tight,and the blade, by reason of its being engaged for a large part of itssurface when it is clamped in position, is

not subjected, at any particular point, to a strain sufficient to causefracture which would easily occur if this were not the case, in view ofthe thin blades that are used in the razor.

Having thus described my invention, what I claim is 1. A safety razorcomprising a fixed guard, ears on the sides of the guard, fingersextending inwardly from the sides of the guard in front of the ears, thefront of the guard being a support and a fender for a blade, the frontof the guard being elevated, a clamping plate pivoted to the ears andnormally extending toward the front of the guard, a thin flat-blade witha reinforced back having its thin portion resting on the front of theguard and under the fingers, the clamping plate having part of its topsurface depressed to receive the reinforced back of the blade, and ahandle in screw-threaded engagement with the handle and forcing theclamping plate against the thin and the reinforced part of the blade tolock the thin part of the blade against the fingers.

2. A safety razor comprising a guard having fingers extending inwardlyfrom its side edges, the guard having its front part elevated, a bladehaving a thin fiat body portion with a reinforced back, the thin portionof the blade resting on the front part of the guard and under thefingers, a clamping plate swinging on the guard and having its endengaging the thin part of the blade to lock the blade against thefingers, the clamping plate havlng a depressed portion to receive thereinforced back of the blade, and a handle forcing and locking theclamping plate against the blade.

In testimony, that I claim the foregoing, I have hereunto set my handthis 5th day of December, 1910.
